Long Range Performance.

Long Range Performance. The Primex 120 and Primex 120W cameras offer OptiTrack’s longest camera-to-marker range for Passive and Active markers. OptiTrack accuracy with more range enables huge tracking volumes for a wider variety of training and simulation scenarios, extreme ground or aerial robotic facilities, larger cinematic virtual production studios and more.

Primex 120 compared to the Slimx 120

Small footprint, lightweight. The Slim^x 120’s shallow profile, light weight and invisible IR illumination are perfect for applications which require a discreet tracking system such as location-based virtual reality and cinematic virtual production .

Slimx equals precision.

Slim^x equals precision. Slim^x cameras are designed and manufactured in-house at OptiTrack’s headquarters in Oregon to ensure our exacting quality standards are met. We design lenses with low-distortion and true 10-bit grayscale depth sensor processing which reduces noise and improves precision—resulting in perfectly crisp images, better centroids and better 3D accuracy.

Mix and match cameras. Systems can pair Slim^x 120 cameras with any other Prime^x or Prime Color cameras to create the optimal infrared configuration for any use case and deliver the highest 3D tracking accuracy to any environment.

300 FPS

High frame rate capture. The Slim^x 120’s 300 FPS capture rate and image stopping global shutter can be used when your application requires Prime Series precision for movement speeds above 150mph.

“Fast glass” lense. We custom design our own super low distortion, “fast glass” lenses for optimal marker tracking. The Slim^x 120’s standard 12mm lens is treated with a wide band anti-reflective coating, which dramatically increases light transmission to the imager, yielding larger volumes and more precise 3D data

Choose the wider-view option. For wider volumes that demand elite accuracy, the Slim^x 120 is also available with a 65° x 51° 18mm wide-view lens. The additional Field of View lets users deploy fewer cameras to capture movement in wider areas.

On-camera status indicator.

On-camera status indicator. Slim^x cameras can keep users informed with definable color LED indicator. Recording a performance? Everyone on set knows the system is recording. Select a camera? It instantly changes color. Have your own idea? Simple software controls help you make it so.

Full resolution grayscale reference video. All Slim^x cameras can be used as a reference video source – with synchronized, calibrated 3D overlay. Deliver and/or record full resolution, full frame rate video with 3D overlay of markers, rigid bodies, skeletons, etc.

External sync in/out, Genlock, and Time Code. Synchronize any SlimX, Prime and PrimeX cameras to any signal or source with the eSync 2 with all the functionality and flexibility you’d expect with a professional tracking system. Cameras sync to dozens of sources including a professional cameras’ Genlock signal, where record and other event triggering can be managed from general purpose inputs and software commands.

Use the sync output signal as a master or to trigger force plates, EMGs and National Instrument DAQs for flexible yet precise hardware synchronization. Highly accurate frame timing can also be achieved with SMTPE Time Code for ease in editing and logging. OptiTrack’s free and open SDK allows for further customization within the timing protocols.

Expert system configuration for any space. OptiTrack has built over 30,000 tracking systems in areas of all shapes and sizes. Our experts can help guide you on the most economical and suitable tracking system for your needs—for today and the future.

It’s more than just cameras. Slim^x cameras work hand-in-hand with OptiTrack’s Motive 3D motion capture software featuring Trained Markersets, Continuous Calibration, Skeletal Solver and more. The Slim^x cameras and Motive enable users to see and analyze tracking data to inform everything from robotics and movement sciences to video game animation, cinematic virtual production and location-based virtual reality.
